C++ (Cpp) CmndResults Examples

Example #1

File: archinfo_linux.c Project: chos9/sage

int ProbeNCPU()
{
   int ncpu = 0;
   char *reslns, res[1024];

   #if 0
   if (mach == Dec21264 || mach == Dec21164 || mach == Dec21064)
   {
      if ( !CmndOneLine(NULL, "fgrep 'cpus detected' /proc/cpuinfo", res) )
         ncpu = GetLastInt(res);
   }
   #endif
   if (!ncpu)
   {
      reslns = CmndResults(NULL, "grep '^processor' /proc/cpuinfo");
      if (reslns) ncpu = fNumLines(reslns);
   }
   return(ncpu);
}

Example #2

int CmndOneLine(char *cmnd, char *ln)
/*
 * executes a system call with contents of cmnd, returns the output in ln;
 * Returns value returned by system call
 */
